dc.description.abstract | In the present study, the use of heterogeneous photocatalysis TiO2/UV coupled to an activated sludge reactor was evaluated
as an alternative treatment for the leachate coming from a Landfll, located in Cucuta (Colombia). TiO2 (Degussa P-25)
between 100 and 600 mg.L−1 was used as a catalyst, semi-continuous type reactors for the photocatalysis, a batch for the
biological stage, UV light with accumulated energies from 20 to 60 kJ.L−1 were also used, a constant concentration of
H2O2 was used as an adjuvant in all tests. The research consisted of four main phases: leachate characterization, biological
treatment, optimization of photocatalytic and AOP-biological coupling. For the optimization of the photocatalytic step, an
experimental design was carried out through the statistical program Statgraphics Centurion XV of factorial type 3^2 (3
levels 2 variables), modeling the results by means of a response surface, the variables of the pH and the concentration of the
catalyst were included, having this as input for the response of interest the percentage (%) of DOC removal. The biological
process itself provided a removal of 38 and 24% for COD and DOC, respectively. The AOP-biological coupling provided
a removal of 68 and 76% in terms of COD and DOC, respectively. Thus, the coupling signifcantly improves the overall
efciency of the process by more than 50%, which represents a promising improvement compared to the removal of organic
matter for the treatment of the same type of water using only the biological process. The results show a viable alternative
for the treatment of leachate because higher removal levels are achieved in residence times, which are considered shorter
than the ones in conventional processes. | eng |
